AEHR Sells Off Hard as Shorts Hold Firm and Options Flip Bullish

AEHR enters the week before its November 2 earnings report with a 28% loss over five trading days, a short base stubbornly near 18% of float, and an options market that has abruptly pivoted away from defensiveness.

The options shift is the most striking signal this week. After months of running well above its 20-day average, the put/call ratio has collapsed to 0.74, more than three standard deviations below that mean of 0.86. At the 52-week low end of the range, this reading points to unusually heavy call buying relative to puts, an aggressive posture into a stock that just lost more than a quarter of its value in a week. Whether that reflects genuine conviction or a speculative bet on a violent short-covering bounce before earnings is impossible to say from the ratio alone, but the divergence between the price action and the options positioning is sharp.

The short story is less dramatic but still meaningful. Short interest has crept up about 13% over the past month and now stands at roughly 18% of the free float, a genuinely elevated level for a mid-sized semiconductor equipment name. The week's change was barely half a percent, so there was no mass covering into the selloff. Short sellers, in other words, did not exit. They stayed. Borrow cost ticked up 45% on the week to 0.53%, but remains low in absolute terms, well below levels that would create any squeeze pressure. Availability is ample at 227% of short interest, meaning the lending pool holds more than twice the shares currently borrowed, so there is no mechanical constraint preventing new shorts from adding. The short score of 61.3 sits in the 8th percentile for sector rank, a bearish positioning signal within semiconductors.

The Street's bullish consensus looks increasingly at odds with where the stock is trading. Six buy ratings and a consensus target near $128 compare with a current price of $60.60, implying the Street sees a near doubling from here. The two most recent analyst actions, an Oppenheimer initiation at Outperform in September and a Jefferies Buy initiation in August with a $175 target, were written before the October earnings miss that sent the stock down 10% on the day and 30% over the following five sessions. Those targets will almost certainly be revised before the November print, but no updates have landed yet. The 30-day trailing P/E has compressed sharply, falling nearly 29 points over the past month as the price dropped faster than estimates moved, and EV/EBITDA has fallen about 1.6 points over the same period.

Peers moved broadly lower on the week but not as sharply as AEHR. FORM fell 25% and COHU 25.5%, close to AEHR's drop, while CAMT and ENTG held closer to 15 to 16% losses. POWI held up best among the group, down less than 10% on the week. AEHR's correlation to the peer group runs in the 70 to 75% range, so some of this week's selloff is sector-wide, but the magnitude of AEHR's move suggests a company-specific factor layered on top of the broader pressure.

Retail attention has spiked. The Wikipedia views and ORTEX page traffic signal for AEHR shows a z-score of 3.6 against its own 90-day history, the highest reading in the alt data for this name. That kind of retail attention spike often follows a violent price move rather than preceding it, but it does indicate the stock is on a lot of screens right now. No insider trading data from the EDGAR Form 4 filings shows a meaningful cluster heading into this report. Among larger holders, BlackRock added 372,000 shares as of September 30, and Jane Street filed a 13G at 5.1% in July. Both are passive or trading-book positions rather than conviction signals.

With earnings confirmed for November 2, fourteen days away, the key question is how much of the October post-earnings damage will be reflected in revised guidance versus already-flagged demand softness in silicon carbide burn-in volumes. The prior print produced a 10% drop on day one and a 30% loss over the following week, so the bar for a relief rally is set high, and the options market's abrupt turn toward calls is the one positioning signal worth watching into that date.
